Hauv plawv ntawm cov chaw tsim hluav taws xob, cov gearboxes ua lub luag haujlwm tseem ceeb hauv kev hloov pauv lub zog tshuab mus rau hauv lub zog hluav taws xob. Ntawm ntau yam khoom hauv cov gearboxes no, cov iav bevel thiabcov iav helicalsawv tawm ua cov neeg tsim kho tshiab tseem ceeb hauv kev xa hluav taws xob.
 Cov iav bevel, paub txog lawv lub peev xwm hloov qhov kev taw qhia ntawm kev tig, yog qhov tseem ceeb hauv cov gearboxes fais fab. Lawv cov qauv hniav tshwj xeeb tso cai rau kev hloov pauv fais fab du thiab zoo, txo qis kev co thiab suab nrov. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov qhov chaw tsawg thiab qhov tseeb yog qhov tseem ceeb.
cov iav helical, ntawm qhov tod tes, muab kev sib xyaw ua ke ntawm kev ua haujlwm zoo thiab lub zog. Lawv cov qauv hniav sib ntswg txo qhov kev sib txhuam thiab kev hnav, ua kom lub neej ntawm lub gearbox ntev dua. Ntxiv mus, cov iav helical tuaj yeem xa cov torques siab dua thiab ua haujlwm ntawm qhov ceev dua piv rau cov iav ncaj, ua rau lawv yog qhov kev xaiv zoo rau cov ntawv thov hnyav hauv cov chaw tsim hluav taws xob.

Cov kev tsim kho tshiab tsis ntev los no hauv bevel thiabcov iav helicalkev tsim qauv tau txhim kho lawv cov kev ua tau zoo ntxiv. Cov ntaub ntawv siab heev, xws li cov hlau nplaum muaj zog thiab cov khoom sib xyaw, tau raug suav nrog los txhim kho kev ruaj khov thiab kev tiv taus kev hnav. Tsis tas li ntawd, cov txheej txheem tsim khoom meej, suav nrog kev tsim qauv siv computer (CAD) thiab kev siv computer tswj tus lej (CNC) machining, xyuas kom meej tias txhua lub iav tau ua raws li cov lus qhia tseeb.

Cov kev tsim kho tshiab no tsis yog tsuas yog txhim kho qhov ua tau zoo ntawm kev xa hluav taws xob xwb tab sis kuj txo qhov yuav tsum tau saib xyuas thiab cov nqi ua haujlwm. Los ntawm kev ua kom zoo dua cov hniav iav thiab txo qhov sib txhuam, cov gearboxes niaj hnub no muaj peev xwm ua haujlwm tau ntsiag to thiab du, txo qhov tsis ua haujlwm thiab txhim kho kev ua haujlwm ntawm cov nroj tsuag.
Xaus lus, cov iav bevel thiab cov iav helical yog cov khoom tseem ceeb hauv cov gearboxes fais fab, tsav tsheb kev tsim kho tshiab hauv kev xa hluav taws xob. Raws li thev naus laus zis txuas ntxiv mus, peb tuaj yeem cia siab tias yuav muaj kev txhim kho ntau dua hauv kev tsim iav thiab kev ua tau zoo, thaum kawg pab txhawb kev ntseeg siab thiab kev ua haujlwm ntawm peb cov kab ke tsim hluav taws xob.
